How car tax is calculated

Current rules for car tax, or Vehicle Excise Duty (VED), are based on a vehicle’s official tail-pipe CO2 emissions and list price. There are thirteen CO2 tax bands which relate to different emissions levels and amounts of car tax payable. The list price influences whether the buyer needs to pay the Standard Rate or Premium Rate, with those vehicles with a list of £40,000 or more paying the latter for years two to six.

Cars registered from 01 April 2017, VED for the first 12 months is covered by a First Year Rate (FYR) which is directly linked to a car's CO2 emissions. New diesel cars registered from 01 April 2018 not meeting the real driving emissions step 2 (RDE2) standard for air quality (NOx) also have to pay a FYR supplement to the effect that these cars go up by one VED band.

For cars registered between March 2001 and March 2017, car tax rates are based on car tax bands A to M, each band being defined by tailpipe CO2 emissions as measured on the official test. Different levels of VED are payable for each band, with the lowest emission vehicles in Band A charged nothing, moving up incrementally so that those with the highest CO2 emissions in Band M pay the most tax.

For cars registered before 01 March 2001, car tax is charged according to engine size as measured in cubic centimeters or 'cc'. There is one rate for engines up to 1,549cc and one for 1,550cc and over.
